I think it's a bit complicated since the EFS contains the IMEI and other info that is device-specific.
That's why you don't see a "flash this and your EFS will be all good" package.
In the old days of S1, flashing a full stock rom and full wipe would restore the IMEI, but that's not likely the case here.
I'd bring it to a service center after restoring to stock.
EDIT: maybe this helps?

Change the partition to the one in the S5 G900H
lrwxrwxrwx root root EFS -> /dev/block/mmcblk0p3
I dont have CWM recovery...can i do that from stock whitout CWM?
I think it needs CWM to work...
If you still have your warranty (Knox flag 0x0) then I'd go to the service center instead of trying to repair it myself.

[/QUOTE][THANK YOU TO ALL OF YOU!!!!! Its aliveeeeeeeeeeeeeeeeeeeeeeeee!!!!!! QUOTE=drakester09;52583287]Flash CWM using Odin (search for it in the Development forums), since you already tripped Knox it doesn't matter if you flash a custom recovery. Then try the fix.

I dont know...i buy the phone unbranded...flash it,and lose him...with your help i could relive it...but now doesnt have signal...
I came from a Sony Xperia Z...i did anything to that phone and never have this kind of troubles... I hate samsung! Damn it!
So bad luck mine...
It depends, did you flash a G900H stock rom? You should flash a full stock image and see what happens.
Did you flash any custom rom in your phone? They currently available ones as of today are for the Snapdragon variant (G900F/I/etc), the G900H is Exynos and currently has no custom roms.
I didn't had any sort of issues with mine.
Sir, as i told you, you fixed the bootloop only with this mentioned method. but it will not fix your EFS partition, so no signal!
Here in the country that i live...(Uruguay) doesnt have a official samsung center to fix my phone issue.
But...recently i had one idea...
I have a friend in the phone company...if he put the new imei,(that the process of recovery of the efs generate)like my official imei.
That will work?
I know that is ilegal...but,i'm desperated...and friends are friends.
I dont have CWM recovery...can i do that from stock whitout CWM?
